背景和目的：缺乏令人信服的证据支持使用磁共振成像（MRI）作为评估颈椎矢状位的有效工具。本研究旨在分析颈椎矢状面X线片和MRI在颈椎间盘突出症患者中的差异和相关性，并确定MRI是否可以替代颈椎X线片测量颈椎矢状面参数。每例患者均接受颈椎X线和MRI检查。测量并比较X线和MRI上颈椎矢状面参数：C2-C7 Cobb角、C2-C7矢状面垂直轴（C2-C7 SVA）、颈椎倾斜（CT）、T1斜率（T1 S）和颈部倾斜（NT）。结果：C2-C7 Cobb角、C2-C7 SVA、CT、T1 S值X线片均大于MRI（P
Background and Objectives: Convincing evidence supporting the use of magnetic resonance imaging (MRI) as an effective tool for evaluating cervical sagittal alignment is lacking. This study aims to analyze the differences and correlations between cervical sagittal parameters on x-ray and MRI in patients with cervical disc herniation and to determine whether MRI could substitute for cervical x-ray for measurement of cervical sagittal parameters.Methods: One hundred forty-three adults with cervical disc herniation were recruited. Each patient had both an x-ray and MRI examination of the cervical spine. The cervical sagittal parameters were measured and compared on x-ray and MRI including: C2-C7 Cobb angle, C2-C7 sagittal vertical axis (C2-C7 SVA), cervical tilt (CT), T1 Slope (T1S), and neck tilt (NT). The data were analyzed using a paired-samples t test, a Pearson correlation test, and linear regression.Results: The values of C2-C7 Cobb angle, C2-C7 SVA, CT and T1S on X-ray were larger than those on MRI (P
